I've been vegging my plant for almost 5 weeks, but one of my plants seems to be dying for no apparent reason. All the plants get the same amount of nutes and water. I'm growing with a 600 Watt MH/HPS Roots organic soil + nutes, and I watered my plants 3 days ago. Now all my plants have a little bit of yellow but not enough for me to worry about. What's wrong with my plant? the wilting plant is the dying one I think The other two are what all the other plants look like.
Wilting is from over watering or under watering , it will pick up once u stop over or under watering , the soil u r using Is low in nitrogen N , so u need to put a bit of nutrients in ur next watering something with more N P then K . Example 6-4-3 Also u should be good to go for flowering as 4-6weeks is the normal over that ur plant gets too tall.
